ft is to be understood that the drawings are illustrative rather than restrictive and are not intended to be interpreted to limit the scope of the appended claims to the construction shown in detail; on the other hand, modifications and equivalents within the spirit of the invention and the scope of the claims when properly interpreted in the light of the prior art are intended tov be included therein. y f

-I claim:- 1 I v "1. A collapsible vehicle including a collapsible body, spaced relatively movable body 7 frames to which the body is secured and throughwhich the body is collapsed and extended, a scissor mechanism between and connected to said frames, a handle for the vehicle pivotally connected to one of said frames, an operating link between the handle and one-of the levers of the scissor mechaand one of said body frames. I

2; A collapsible vehicle comprising a C01 lapsible body carried between two body-' frame members movable in parallel relationship, a scissor mechanism interposed between the two frames, a folding propelling handle pivoted to the propelling end of-the lower frame-member, 'pull-and -push operating links interposed between the'handle and the scissor mechanism and adapted to transmoveme'nt for expanding andcollap'sing the saidmechanism, and locking stays interposed between the upper frame and v the handle.

3, A collapsible vehicle comprising a. collapsible body carried between two" frame members movable in parallel relationship, a

scissor mechanism interposed between, the

two frames, the forward ends of each member of the sald scissors mechanism having a Slld-r ing interconnection with the respectiveupper and lower frame members, a. folding handle pivoted to the lower frame member, pull-andpush operatinglin'ks interposed'between the handle and the scissors mechanism, and fold ing butt-hinged locking stays interposed be- 7 tween the upper frame and the handle.

In testimony whereof I aflix my signature. WALTER LINES.
